Specification of Letters Patent.

Patented Sept. 9, 1919.

Application led September 10, 1918. Serial No. 253,449.

To all `11i/tom. may concern.'

lkle it known that I, BENJAMIN F. CHIL- nnuss, a citizen of the UnitedStates, and a resident ol" Lynchburg, in the county ot' (falnpbell andState of Virginia, have invented new and use'lul Improvements inPorcelators, ol which the following `is a pecl licati on.

This invention relates to percolators and has particular reference tothat class of percolators adapted to be used in connection with theconventional Aform of collec pots.

An important object o'l the invention is to novide in a device oi? thecharacter descrilred, a means whereby the device Vas a whole may bereadily adapted lto use in con ncction with various sized coffee potswithout altering or changing the construction ol the coffee pot or thedevice embodying my invention.

A. further object of the invention `is to` provide in a device of theabove mentioned character, a means whereby fthe various elementscomprising the invention may be held in a correct position with respectto each other.

A `further object of the invention is to provide a device of the abovementioned character which is strong, durable, reliable in operation andinexpensive to manufacture.

Other'objects and advantages of' the inventiion will be apparent duringthe course ofi the vfollowing description.

In the accompanying drawings forming a part oil this specification andin which like numerals are employed to designate like parts throughoutthe saine,

Figure 1 is a central, vertical, sectional view ol a coffee pot showingthe device embodying my `invention associated therewith.

Fig. 2 is a horizontal, sectional view taken on a line 2 2 of Fig. 1,and

Fig. 3 is a horizontal sectional view taken on a line 8-3 of Fi 1.

In the drawings wierein for the purpose of illustration is shown apreferred form oi my invention, the numeral 5 indicates, as a whole, acotlee pot provided with a spout 6, a handle 7, and a conventional formof elo sure 8.

Upon the col'ee pot 5 there is arranged a container 9 having formed atits upper edge a lip 1l). This container is preferabl7 of `glass and isprovided at its lower edge with an elongated flange 1l. which extends anappreciable distance into the coffee pot 5 as clearly shown in Fig. l.The liange 11 `is provided at its lower edge with a rougheued peripheral'face as shown at 12 ,in or der that the strainer cloth 13 may be thoruoughly secured in position upon the liange 11 when a metallic ring 14:is pissed over` the flange 1l. This strainer cloth 13 is preferably oitlflannel. The container9 is pro vided adjacent the 'flange l1 with aplu- 1ality of peripheral grooves l5 which are adapted to retain thecontainer 9 in an upright position when placed upon the coifee pot 5. Byreason of the fact that `the l grooves 15 are formed upon the surface ofthe container 9 whose walls are grooved, the container 9 is adapted tobe held in position upon any reasonably large or small colee pot.

Upon the container 9 there is disposed a reservoir 1G having its bottom17 provided with an annular ring 18, within which the lip` 10 ol thecontainer 9 is adapted to lit. The ring 1S serves as a means forretaining the reservoir 16 in a desired position upon the container 9.The reservoir 16 is provided with a conventional closure 19 and withinthe bottom 17 there is formed an aperture Q0 leading into the container9.

In use ground colfee is placed within the container 9, the containerbeing placed upon the coiliee pot 5 in the position clearly shown inFig. 1. A desired quantity of water is then placed within the reservoir16,

the amount of water depending upon the Y amount of coiiee groundsdeposited within the container 9 and the quantity of cofee desired to bemade. The reservoir containing the water is then placed upon thecontainer 9 whereupon the water is directed into the container 9 andallowed to percolate through the coffee grounds and the strainer cloth.13 whereupon it is collected in the coffee pot 5. i

I prefer to use a cloth 13 sufficiently thick to prevent the water whendeposited into the container 9 from the reservoir 16 from immediatelyflowing through the coffee grounds into the coffee pot 5, in whichinstance` the water will rise approximately three or four inches untilthe pressure is sufficient to cause percolation, thereby giving thecoffee grounds time to become thoroughly saturated and also giving thecontainer 9, when glass is used, sufficient time to become gradually hotthereby eliminating the probability of its becoming broken due to suddenheating thereof and at the same time enabling me to use a quality ofglass havinfr such characteristics as would cause it to withstand theheat transmitted thereto as a result of boiling water being rapidlydeposited into the container 9.

^ It is to be understood that the form of my invention herewith shownand described is to be taken as a preferred example of the same, andthat various changes in the shape, size, and arrangement of parts m-aybe resorted to without departing from the spirit of the invention or thescope of the subjoined claims.

It is to be understood that the form of my invention herewith shown anddescribed is to be taken as a preferred example of the same, and thatvarious changes in the shape, size and arrangement of lparts may beresorted to without departing from the spirit of the invention or thescope ofthe sub joined claim.

Having thus described my invention what 4I claim is:

A percolator for coffee pots comprising a substantially spherical shapedcontainer adapted to be seated upon the top of the coffee pot, adepending cylindrical flange secured to said container and adapted toeX- tend into the coffee pot, said fl( nge being diametrically smallerthan said container, said container being provided relatively near saidflange with a plurality of grooves, each groove being adapted to receivethe upper end of a coffee pot having a corresponding circumference tosnugly fitin said groove, said flange being provided at its lower endwith a roughened peripheral face, an annular ring encircling saidflange, a strainer cloth having its peripheral edge confined betweensaid ring and said roughened face, and a reservoir removably mountedupon said container, said reservoir having `its bottom providedcentrally with an opening to permit the contents thereof to flow fromthe reservoir into the container whereupon said contents is permitted topass into the coffee pot through said strainer cloth.
